This page will contain information of a technical nature for Aeronca enthusiasts.  It's under construction.  Right now, I just have a few items, but the Tech Info page will grow over time...

Tech Info:

• Brake Cables - do you have the correct brake cable on your Champ or Chief?  An improper cable could cause an embarrassing moment.  Here's info on what to look for.  Added 3/11/01, Updated 10/27/04.
• Goodyear Brake Return Springs.  The Goodyear mechanical disc brakes on many of our Aeroncas require some special care.  One area of interest is the return spring that pulls the puck away from the disk when the brakes are released.  A stronger spring allows the brakes to be adjusted so that the puck sits closer to the disc in the released position, improving performance when the brakes are applied.  Here are photos of two different types of return springs.  The spring in Photo #1 does the better job of keeping the puck away from the disc when released. Both photos (and the information) are courtesy of Richard Starr.  Photo #3 shows the spring on my Chief, N86176, the same type of spring as in photo #1. This photo is taken from the front, with the wheel and disk removed.
